TECHNICAL FIELD

The present disclosure relates generally to lighting solutions, and moreparticularly to a luminaire with a releasably lockable wire cover.

BACKGROUND

Luminaires include wire covers that are configured to house and securelyretain electronic components within the luminaires and/or to provide aconcealed path for the electrical conductors (e.g., electrical wires) inthe luminaire. Typically, the luminaires are shipped with the wirecovers being removably coupled to the housing of the luminaires and/orwith the electronic components disposed in electronics enclosuresdefined by the wire covers. However, the wire covers are formed usingthin and/or flexible material. Consequently, vibrations and/or otherimpacts on the luminaire during shipping may cause the wire cover toflex and be decoupled (pop out) from the luminaire. Such a decoupling ofthe wire cover during shipping of the luminaire may cause damage to theluminaire and/or the electronic components that are securely retained bythe wire cover.

The decoupling of the wire cover from the luminaire during shipping maybe prevented by locking the wire cover to the luminaire using fastenerssuch as screws, for example. However, fastening the wire cover to theluminaire using screws may require the use of tools or other additionalequipment for both installation and removal of the wire cover.

This background information is provided to reveal information believedto be of possible relevance to the present disclosure. No admission isnecessarily intended, nor should be construed, that any of the precedinginformation constitutes prior art against the present disclosure.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The present disclosure describes a luminaire with a releasably lockablewire cover. The luminaire and the wire cover of the present disclosureare configured to be releasably locked to each other such that theyremain locked during shipment and handling. That is, the luminaire andthe wire cover are configured such that once the wire cover isreleasably locked to the luminaire, the wire cover does not decouplefrom the luminaire till a user releases the locked wire cover from theluminaire. So, a wire cover of the present disclosure that is releasablylocked to the luminaire does not decouple from the luminaire due tovibrations or the other impacts on the luminaire during shipping (e.g.,from factory to field) and handling thereof. Further, the luminaire andthe wire cover are configured for toolless coupling and decoupling,thereby eliminating any need for tools to lock and hold the wire coverto the luminaire and/or to decouple the wire cover from the luminaire.Furthermore, the luminaire and the wire cover are configured such thatthe coupling of the wire cover with the luminaire creates an electricalgrounding path for the luminaire and/or the electronic components thatare disposed in an electronics enclosure defined by the wire cover.

In one example, the luminaire includes a back plate that has a first tabthat defines a tab receiving cavity. The first tab includes a firstmating feature. Further, the luminaire includes a wire cover that has asecond tab that is configured to be disposed in the tab receiving cavityof the back plate. The second tab of the wire cover includes a secondmating feature. The first mating feature and the second mating featuremay be complementary to each other.

The wire cover is coupled to the back plate by inserting the second tabof the wire cover into the tab receiving cavity defined by the first tabof the back plate. That is, the wire cover may be coupled to (anddecoupled from) the back plate of the luminaire without using any tools.As the second tab of the wire cover is disposed in the tab receivingcavity of the back plate, a second mating feature of the second tab ofthe wire cover engages with the first mating feature of the first tab ofthe back plate to releasably lock the wire cover to the back plate ofthe luminaire. To decouple the wire cover from the back plate, thesecond mating feature of the wire cover must be released from the firstmating feature of the back plate. In said example, as the second matingfeature engages the first mating feature, an audible sound may becreated to confirm and to ensure an end user that the two parts, i.e.,the wire cover and the back plate are properly attached. Further, insome examples, when the second mating feature engages the first matingfeature, an electrical grounding path may be created through the contactbetween the first and second mating features.

Example embodiments of the luminaire with the releasably lockable wirecover will be described more fully hereinafter with reference to theaccompanying drawings that describe representative embodiments of thepresent technology. If a component of a figure is described but notexpressly shown or labeled in that figure, the label used for acorresponding component in another figure can be inferred to thatcomponent.

Such termsare not meant to denote a preference or a particular orientation, andare not meant to limit embodiments of the luminaire. In the followingdetailed description of the example embodiments, numerous specificdetails are set forth in order to provide a more thorough understandingof the present disclosure. However, it will be apparent to one ofordinary skill in the art that the luminaire with the releasablylockable wire cover of the present disclosure may be practiced withoutthese specific details. In other instances, well-known features have notbeen described in detail to avoid unnecessarily complicating thedescription.

Turning now to the figures, example embodiments of an example luminairewith an example releasably lockable wire cover (hereinafter ‘wirecover’) will be described in connection with FIGS. 1-8. Referring toFIGS. 1-8, an example luminaire 100 includes a back plate 102, a lens104 that is coupled to the back plate 102, and end caps 106 that aredisposed on opposite ends (108 a, 108 b) of the luminaire 100 andcoupled to the back plate 102 and the lens 104. The end caps 106 may beconfigured to cover the ends (e.g., laterals ends 108 a, 108 b) of theluminaire 100 and support and securely retain a portion of the lens 104(e.g., edges) therein.

The back plate 102, the lens 104, and the end caps 106 are coupled toeach other and arranged such that they define a luminaire internalcavity 202 (shown in FIG. 2) that is configured to house a light engineof the luminaire therein. The light engine may include one or more lightsource assemblies 220 (shown in FIG. 6) and/or electronic componentsassociated with the luminaire 100 that are configured to supply power tothe light source assemblies 220.

As illustrated in FIGS. 2 and 3, the back plate 102 may include a base250 and sidewalls 252 that extend substantially perpendicularly from atleast a portion of a perimeter of the base 250. The base 250 may includeone or more mounting apertures 254 that are configured to receivemounting features therethrough to mount the luminaire 100 to anappropriate mounting surface (e.g., ceiling, wall, etc.). Further, thebase 250 may include one or more locking tabs 256, where each lockingtab 256 defines a tab receiving cavity 258. The locking tabs 256 of theback plate 102 may be stamped into or formed from a portion of the base250 of the back plate 102 such that the locking tabs 256 project outfrom the base 250 of the back plate 102 to define the tab receivingcavity 258. Each locking tab 256 may include one or more mating features260 that are formed therein.

In addition to the back plate 102, the lens 104, and the end caps 106;the luminaire 100 may include a wire cover 204 (shown in FIG. 2) that isdisposed in the luminaire internal cavity 202 and removably coupled tothe back plate 102 of the luminaire 100. As illustrated in FIGS. 2-8,the example wire cover 204 may include a base wall 206 and sidewalls 208that extend angularly or substantially perpendicular to the base wallfrom at least a portion of the perimeter of the base wall 206. The innersurface 212 of the base wall 206 and the sidewalls 208 may define anelectronics cavity 210 that is open at the lateral ends (210 a, 210 b)thereof and at the side that is opposite to the base wall 206. The backplate 102 and the end caps 106 may enclose the electronics cavity 210.That is, the back plate 102 may cover the open side of the wire cover204 that is opposite to the base wall 206 when the wire cover 204 iscoupled to the back plate 102 and the end caps 106 may cover the openlateral ends (210 a, 210 b) of the wire cover 204 when the end caps 106are coupled to the back plate 104. The electronics cavity 210 that isdefined by the wire cover 204 may be configured to house and conceal oneor more electronic components and/or electrical conductors (e.g.,electrical wires) associated with the luminaire 100 therein. Exampleelectronic components may include, but are not limited to, a driver, aballast, etc.

Further, the wire cover 204 may include coupling tabs 216 that aredisposed on an outer surface 214 of the base wall 206 and/or thesidewalk 206 thereof. The coupling tabs 216 may be configured tosecurely couple and retain a light source assembly 220 on the wire cover204 as illustrated in FIG. 6. In some cases, one or more fasteningdevices 288 (e.g., screws) can be used, in addition to the coupling tabs216, to help secure a light source assembly 220 to the wire cover 204.In such cases, each fastening device 288 can be inserted into a couplingfeature 289 (in this case, an aperture), as shown in FIG. 4, in the basewall 206 of the wire cover 204. In the example embodiment illustrated inFIG. 6, the light source assembly 220 may include an array of lightemitting diodes (LEDs) 222 disposed on a substrate 224 such as a printedcircuit board, for example. However, in other example embodiments, thelight source assembly 220 may include any other appropriate lightsource, such as fluorescent lamps, halogen lamps, other point lightsources, printed LEDs, etc., without departing from a broader scope ofthe present disclosure.

In other words, the wire cover 204 may be configured such that an innersurface 212 thereof defines an electronics cavity that is configured tohouse electronics components and/or electrical conductors therein, whilethe outer surface 214 thereof may define a light source attachmentsurface that is configured to securely retain one or more light sourceassemblies 220 thereon.

Additionally, the wire cover 204 may include flange sections 226 thatextend outward from the outer edge of the sidewalls 208. The flangesections 226 may operate as the feet of the wire cover 204 that rest onthe back plate 102 when the wire cover 204 is coupled to the back plate102. Further, the wire cover 204 may include one or more cover tabs 228that are disposed in between the flange sections 226. In some exampleembodiments, the cover tabs 228 may be defined by the flange sections226. In other example embodiments, the cover tabs 228 may be separatefrom the flange sections 226 and may not be defined by the flangesections. Further, in some example embodiments, the wire cover 204 maynot include the flange 226. Instead, in said example embodiments, thewire cover 204 may only include the cover tabs 228. Each cover tab 228may include one or more mating features 230.

In one example, the mating features 230 of the cover tab 228 may becomplementary to the mating features 260 of the locking tabs 256 of theback plate 102. In one example embodiment, as illustrated in FIGS. 2-8,the mating features 230 of the cover tabs 228 and the mating features260 of the locking tabs 256 may include dimples that are substantiallyhemispherical in shape. That is, each mating feature (230, 260) of thecover tab 228 and the locking tab 256 may have a substantially convexouter surface and a substantially concave inner surface. In anotherexample embodiment, the mating features (230, 260) may be dimples havingany other appropriate shape without departing from a broader scope ofthe present disclosure. For example, the mating features (230, 260) mayhave a triangular or pyramid shape or any other appropriate shape wherethe surfaces meet at an apex. In yet another example embodiment, themating features (230, 260) may include a slot and snap fit hook feature,where one mating feature is the slot and the other mating feature is thesnap fit hook.

It is noted that the above-mentioned examples of mating features (230,260) are non-limiting, and the mating features (230, 260) of the wirecover 204 and the back plate 102 of the luminaire 100 can include anyappropriate complementary mating features that allow the wire cover 204to be releasably locked to the back plate 102 without using any tools,e.g., by engaging the mating features 230 of the wire cover 204 with themating features 260 of the back plate 102.

As illustrated in FIGS. 7-8, the wire cover 204 may be disposed in theluminaire internal cavity 202 and coupled to the back plate 102 of theluminaire 100 by inserting the cover tabs 228 of the wire cover 204 intothe respective tab receiving cavities 258 defined by the locking tabs256 of the back plate 102 till the mating features 230 of the cover tabs228 engage the respective mating features 260 of the locking tabs 256.When the mating features 230 of the cover tabs 228 of the wire cover 204engage the respective mating features 260 of the locking tabs 256 of theback plate 102, the wire cover 204 may be releasably locked to the backplate 102 of the luminaire. Further, when the mating features 230 of thecover tabs 228 of the wire cover 204 engage the respective matingfeatures 260 of the locking tabs 256 of the back plate 102, the outersurface of the mating features 230 of the cover tabs 228 may contact theinner surface of the mating features 260 of the locking tabs 256 asillustrated in FIG. 8. In some example embodiments, the contact betweenthe outer surface of the mating features 230 of the cover tabs 228 withthe inner surface of the mating features 260 of the locking tabs 256 maycreate an electrical grounding path for the luminaire 100 (e.g., theelectronic components disposed in the luminaire 100). For example, in anexample embodiment where the mating features (230, 260) are shapedsubstantially like a pyramid, the apex of the mating feature 230 of thecover tabs 228 may cut into the paint and engage the conductive innersurface of the mating features 260 of the locking tabs 256 to form theelectrical grounding path.

To decouple the wire cover 204 from the back plate 102, the matingfeatures 230 of the cover tabs 228 of the wire cover 204 must bedisengaged from the respective mating features 260 of the locking tabs256 of the back plate 102. In one or more example embodiments, themating features 230 of the cover tabs 228 may be disengaged from therespective mating features 260 of the locking tabs 256 by applying anappropriate force on the wire cover 204 and/or the back plate 102, e.g.,by a user.

Furthermore, in some example embodiments, when the mating features 230of the cover tabs 228 of the wire cover 204 engage the respective matingfeatures 260 of the locking tabs 256 of the back plate 102, an audiblesound or cue may be generated to confirm or to ensure a user that thewire cover 204 has been releasably locked to the back plate 102 of theluminaire. In one example, the audible sound or cue may be a clicksound. However, in other examples, the audible sound or cue may includeany other appropriate sound without departing from a broader scope ofthe present disclosure.

Even though FIGS. 1-8 illustrate a linear luminaire 100 with a backplate 102 and a wire cover 204 that are substantially rectangular inshape, one of skill in the art can understand and appreciate that inother example embodiments of the present disclosure, any otherappropriate luminaire having a back plate and a wire cover of any otherappropriate shape may be used without departing from a broader scope ofthe present disclosure. Also, even though the present disclosuredescribes that the wire cover 204 is coupled to the back plate 102 ofthe luminaire 100, one of skill in the art can understand and appreciatethat in other example embodiments, the wire cover may be coupled to anyother appropriate portion of the luminaire, for example a housing of theluminaire, without departing from a broader scope of the presentdisclosure provided that the other appropriate portion of the luminaireincludes tabs that define tab receiving openings and comprise matingfeatures that are complementary to the mating features of the wirecover.

Although example embodiments are described herein, it should beappreciated by those skilled in the art that various modifications arewell within the scope and spirit of this disclosure. Those skilled inthe art will appreciate that the example embodiments described hereinare not limited to any specifically discussed application and that theembodiments described herein are illustrative and not restrictive.
